SPECIFICATION forming part of Letters APatent No.1601,065, dated March22, 1898'. Application filed October A30, 1897. Serial No. 656,962. (Nomodel.)

To @ZZ whom it may concern:

Beit known that I, JOSEPH H. SMITH, of Washington, in the District ofOolumbia,have invented certain new and useful Improvements inLawn-Sprinklers; and I do hereby declare the following to be a full,clear, and exact descriptionof the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and usefulirnprovements inlawn-sprinklers.

The object of the invent-ion is, primarily, to provide a simpleandinexpensive sprinkler which will be free of all parts liable to get outof order, and, secondarily, to enable a large area to be sprinkled by asingle device.

The inventionwill be hereinafter fully set forth, and particularlypointed out in the claims. v

In the accompanying drawings, Figure lis a view in side elevation, parts,being in section and the otherv parts broken away. Fig. 2 is a planview of the rotary head. Fig. 3 is a View of the stationary head withparts detached. Fig. 4. is a vertical sectional view of aslightly-modified form. Fig. 5 is a detail thereof.

Referring to the drawings, A designates the sprinkler as an entirety, aa T-joint into which opens a water-supply hose, and ct' a supporting-rodby which the sprinkler can bev positioned at any desired point, thelower end of said rod being forced into the ground.

B is a stationary head which is provided with a depending pipe-sectionb, exteriorly threaded, so as to enter the upper threaded end of T-jointa. In the under side of head Bis a wide transverse groove b and a cutoutb2, forming a water-channel, from each end of which leads a port b3.These ports form outlets and are extended in opposite directions throughand beyond the sides of the groove b2, terminating at their outer endsflush with the llower face of the head B. Within the groove b is fitteda at plate C, preferably formed integral with theupper end ofpipe-section b. Hence water entering from said pipe-section will travelthrough the .channel formed by cut-out b2 and escape in oppositedirections through ports b3. D is the rotary head, which is of circularform, being provided with a riml d, a bottom d', preferably integralwith said rim, and a removable top d2, which is held to the rim byscrew-threads d3. In the center of bottom d is a hole d4, whichaccommodates a boss or circular enlargement d5 -of pipe-section b. Onthe upper surface of this bottom is a circular series of grooves d6,having inclined bottoms, forming'buckets. Water discharged in oppositedirections from the stationary head will strike these buckets and causethe rotation of head'D. In the form shown in Figs. 5 and 6 the waterwill find its escape through a series of perforations` e and a hole e',formed in rim d. When the outfiow is greater than desired, the hole e'may be closed by a plug.

YIn the form shown in Fig. l the water passes up over the stationaryhead and out through a central opening in top d2. In this opening isfitted a T-joint e2, into which are vscrewed the inner ends of two smallpipes e3. These pipes may be of any suitable and desired length, and tothe outer ends thereof are secured oppositely-faced sprayers e4, throughwhich the Water will be emitted in spray form. While this form isdesirable where a large area of ground is to be sprinkled, `yet for allordinary purposes the escape of the water direct through theperforations in the rim of the rotary head will suffice.' When thelateral distributing-pipes are employed, I form a slight depression f inthe top of the stationary head and give a decidedtaper to the uppersurface of the latter. p

The advantages of my invention are apparent'to those skilled in the artto which it appertains.

It'will be seen that a sprinkler constructed as herein described isextremely simple and inexpensive and not liable to readily get out oforder, it being free from all movable parts save the rotary head.

`I claim as my invention- 1. A `lawn-sprinkler comprising a rotary headof circular form having water-outlets, a stationary head inclosed bysaid rotary head having a water-pipe leading into its under side, and achannel in the under side of said stationary head opening laterally atits ends, whereby the water discharged therefrom iinpinging against thebottom of said rotary IOO head will eeet the rotation of the latter,substantially as set forth.

f2. A lawn-sprinkler comprising a rotary head of circular form havingWater-outlets, a stationary head inclosed by said rotary head having achannel in its under side opening at its ends into two lateral,oppositely-extended ports, a plate attached to said head extendingacross said channel, and a Water-pipe opening through said plate intosaid channel, substantially as set forth.

3. A lawn-sprinkler comprising a rotary head of circular form havingwater-outlets and bucket-grooves in its bottom, a stationary headinclosed by said rotary head and having a recess and channel in itsunder side and oppositely-extended lateral ports, one at each end ofsaid channel, a plate fitted in said recess, and a pipe-section extendedfrom said plate through the bottom of said rotary head, substantially asset forth.

4. A lawn-sprinkler comprising a rotary head having a circular bottomformed with a central opening and a series of Watergrooves in its innerface, a top removably secured to said head, astationary head inclosed bysaid rotary head and having a water-channel and oppositely-extendedlateral ports in its underside, and a pipe-section opening into saidchannel and extended through said central openin gin the bottom of saidrotary head, substantially as set forth.

5. The combination with the stationary head having a central water-inletand laterally-extended outlet-ports, of the rotary head inclosing saidstationary head and having an openingin its top and laterally-extendedpipes leading from said opening and having sprayers on their outer ends,substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.

JOSEPH II. SMITH.
